Many motorists in winter refuse personal transport completely or go on it on trips much less often than usual. That is, there are several reasons, and the main thing is the presence of snow on the roads. At the same time, not all drivers care about maintaining the battery in the winter, leaving it connected to the terminals as usual for weeks or months. Such negligence can lead to the complete discharge of the battery or its failure due to the closure of one of the cans. So that this does not happen, you should get acquainted how to store the battery in winter.
Should you remove the battery in winter from the car?
It is believed that automotive batteries in winter need to be removed to save their maximum charge. This statement is true, but not always, in some cases you can do less radical solutions.
In the conditions of "warm winter" (when the air temperature at the vehicle storage is not lowered below -10 degrees) to save the maximum charge of the battery and do not bother with the transfer of the battery, it is recommended to reset one of the terminals of the onboard network from the power supply. We recommend to avoid the risk of the "plus" hit on the mass and short circuit of the on-board network. Due to the removal of one of the terminals from the car battery, it will be possible to strongly reduce the process of the power source discharge.
If the temperature in the place where the car costs, has dropped significantly below -10 degrees Celsius, you should think about transferring the battery to a warmer room. At the same time, you should not forget that from the onboard network of the car, the settings of the electronic systems will be reset.
How to store battery in winter?
The main thing is to remember in the question of the safety of the battery in the winter, this is its position in space. In no case store the battery vertically or "on the side". The power source, dried or flooded with an electrolyte, should always stand horizontally.
To store the battery in winter it is necessary to choose the right place for the following criteria:
- There should not be straight sun rays on the battery housing. That is why, if there is a choice between the storage of the battery in the storage room or on the balcony, it is better to give preference to the pantry or any other "dark" room, where the sun rays do not fall. Danger If the sunlight falls on the battery during its storage is that they are able to cause the deformation of the case, and this will lead to failures in the operation of the power supply after connecting to the car;
- The temperature in the storage location of the battery should be above -5 degrees Celsius. You can leave to winter the power supply in the cellar or basement, where the temperature, if the zero is lowered below, is not much;
- The room should be well ventilated and not having increased air humidity. This is due to the fact that during the self-discharge the battery highlights the mixture of oxygen and hydrogen, which is explosive. With long-term storage, self-discord is inevitable, and its value depends on the air temperature - the higher, the more.
The storage of the battery with an electrolyte requires not only the right selection of the room, but also to prepare it to the "wintering". Many forums write that the electrolyte of the battery should be merged for its best preservation in winter - this is a lie. Moreover, before storage, it is necessary to check the electrolyte level in the battery. If it is reduced, then the result of distilled water into the battery, and after it is to charge it.
Attention: In the battery you can only pour distilled water. In no case do not tighten the water from the tap or the acid, as this can cause unwanted reactions that will lead to the failure of the power source.
Long storage of battery using boric acid without refueling
As a last resort, if it is not possible to charge the battery to the limit values \u200b\u200bin winter, should be used to reduce the self-discharge boric acid. Similarly, you can leave for the storage of the "spare" power supply for the car in the garage or apartment for many months. To reduce the self-discharge into the battery, 5 percent solution of boric acid is poured according to the following system:
Attention: Boric acid susceptible to temperature change, so the battery-filled with it is necessary in a relatively warm place at temperatures above 0 degrees Celsius. However, do not forget that direct solar rays should not fall on the power source body.
The "canned" battery can be stored for more than 15 years at a temperature of 0 degrees Celsius. In warmer conditions, its storage period becomes less. Experts do not recommend storing without checking at temperatures above 20 degrees Celsius battery for more than 9 months.
Restore the working state of the battery after its storage using boric acid follows the instructions below:
- Boric acid slowly merges from the battery - for 15-20 minutes;
- After a complete merging of boric acid, the required volume of electrolyte is poured into the battery, which is a mixture of sulfuric acid with distilled water with a density of 1.83 g / cm 3. To add electrolyte at a temperature of from 15 to 30 degrees Celsius;
After updating the electrolyte in the battery, you must make sure that its density does not fall. To do this, it is better to leave the battery for 40 minutes, after which the density of the electrolyte is measured. If everything is in order, the battery can be installed on the car and be sure that the most inopportune call will not be necessary
I recently wrote an article - about, I pointed out that there is one old "Dedovsky method" check. Just throw off the terminal when the engine running (any, but more convenient) and if the machine does not stall, then the generator is alive. And I immediately went comments that it is impossible to do that everything burns (in the sense of wiring and other electrical). Is it really possible to do that? Also many of my readers are interested in the question - is it possible to remove the battery for a long time, say for several months, for example, for the winter, if the car is not exploited? What let's understand ...
Before talking about the working engine, I want to start with a long-term removal of the battery, for example for the winter, because many beginner drivers do not move in winter, that is, they put the car on a kind of parking lot. To begin with, whether it is necessary to remove the battery
Why remove the battery for the winter
Guys here are all simple - remove not "kill" battery! If the machine is not operated, but the terminals are thrown on the battery, then the digging of the discharge is still present, of course, someone has a lot more leakage, someone is much smaller, but it is present in any case (by the way as it). Also, no need to forget about the currents of the self-discharge, even the most perfect acb can be discharged for a long simple. Yes, that sin to hone, batteries are not always clean on top, that is, mud, moisture may be present on them (for example, atmospheric precipitation, evaporation, etc.), antifreeze and a lot of things. All this can discharge the battery, let it slowly, but right.
Is it possible to shoot for a long time?
For example, after three to four months, the battery may lose 25% of its capacity, and in six months about 50%. If such a discharged battery remains under the hood of the machine for the winter, then it, and so that it is possible to break the case.
Therefore, to remove the battery from the car, let it be a foreign car or our VAZ, gas, UAZ, and so on, with a long parking lot - preferably! Take the battery home, leave in Tambour, storage room, on the balcony in the end and occasionally, at least once a month - two, check the tension from it. If necessary, recharge.
Of course, if you leave the car for two to three weeks, then there is no need for removal, here it will be enough.
What will happen to the car if you removed the battery for a long time? There is such a myth - that all the settings are collected, everything will be reset, to such an extent that almost a new firmware will need to be downloaded!
With responsibility I can say the guys, it is a myth, and nothing more. All basic settings are siled in the on-board computer and forever! And they are energetically independent! It must be understood. If you follow the logic of "such users" if you throw off the terminals from the battery (for a long time, for example - for a week), all information with the ECU including mileage will be thrown. After all, now it is electronic and is located in the electronic control unit. But he is not reset, all because, once again, I emphasize, there is no energy dependence!
Of course, you will reset the tape recorders, time, date, audio equipment settings, but all this is quickly configured and this data is not important for the operation of the car. Also, adaptation with modern automata, but after 50 - 100 km, after starting, the automatic transmission will again remember your ride style, these are the so-called adaptive automatic transmissions.
Therefore, the removal of the battery for a long time from the car, absolutely, will not harm it, this is a fact. Do not believe Ruscas Mount to professionals.
Justice worth noting - That there are difficult, expensive (often representative brands of cars, such as Infinity, Lexus and others), they have a battery removal, complicated and not always recommended to shoot for a long time. All because they can in the car can be up to several control units, and if the main is non-volatile, then the rest have built-in small batteries that need a substantive. If you remove the battery for a long time, from 2 to 6 months, then these small batteries may not be enough. After starting the car, various functions may not work, for example, automatic adjustment of the rear seats and so on. Of course, it is also not critical, but unpleasant!
There are not many such machines from the total mass (literally a few percent), and often in the operating instructions for reducing the battery goes with restrictions! It should be remembered. But in the remaining 95 - 98% of cases, you can not remove without fear.
Is it possible to shoot when the engine running?
Here there are two camps - some say that it is possible and nothing terrible will not be, others that will burn everything you can!
Personally, I think that for a short time it is possible to remove the battery, for example, to launch a neighboring car "Over-Sex" (and there are no wires for chinning), then it is quickly removed and put it back.
By the way, this way can be checked by the generator's performance, here look at my video (if you do not want to wait at the wind at once 14:21 minutes).
But it is worth doing everything very carefully, let's call on points:
- Short circuit . Actually, when the engine works, the electric current is generated by the generator, respectively, the plus terminal is plus, for minus - minus. If you are removing the battery, then in no case cannot be allowed to allow the plus terminal to get in touch with the car body, otherwise there will be a strong closure, then all the wiring and electronics can be sick! After all, the generator can produce sufficiently strong currents. That is, a plus terminal, must be isolated from metal parts of the body, because it is precisely on it, that is, a minus part is connected.
- Voltage drops. Many people wrote me that - "when removing the terminal, the entire electrician (and the matter is not even in a short circuit), but simply from the voltage jump." As I think it is gently to say "not true." Why? I justify - see, the generator is "not a stupid" dynamo machine, it is essentially a very smart unit with her special "". What he does, he tritely stabilizes tension, that is, it does not give it to exceed 14.5 volts bar. After all, in essence, the generator for large revolutions can produce 15 and even 17 volts, such a voltage will be destructive for most devices, so this regulator "stabilizes" cutting off the extra voltage from above. So if we rent a battery, then again nothing terrible will happen, the stress on the network was from 13.8 to 14.5V. And remains. Damn well, what to ride him? If you want to reinforce it a bit, you can give a load in the form of headlights, stoves, heating of glasses and seats, then the voltage will fall by about 13.7 - 14V., That's all! And essentially, the battery is nothing else as the current consumer (load), if it is unshamed - it gets a charging from the generator, if it is charged - it does not get anything! Why should it burn then, please explain?

Many motorists remove the battery from the car, take it home overnight. Do I need to remove the battery from the car in winter Or is it a relic of the past?
One thing can be said for sure - remove the battery from the car Every day there is no point. In winter, life to extend the battery, just a couple of times a month to remove it and fully charge.
Remove the battery And to carry it into heat usually comes when the battery is old. Other and charged battery perfectly tolerate overnight nights and winter and summer.
If the battery can not turn the crankshaft by the morning, then it is to carry it home every day - too troublesome. This is an explicit signal that it is time to purchase a new battery.
When is it worth removing the battery from the car in the winter?
There are situations where the battery is desirable to shoot, even if it is new and charged.
For example, if you do not use the car for a long time, the battery makes sense to get home. For a couple of weeks idle in the cold, even a new battery can sit down.
Also, the battery can be removed if it is necessary to go by car in the morning, and in the street, strong frosts are minus 30-35 degrees. It is better not to risk and make a battery in heat, otherwise in the morning you can not start the car.
Despite its fairly simple device, the car battery still remains one of the most complex and incomprehensible parts of the car. Traditional issues related to its proper operation of motorists are quite a lot, and one of them is the question of whether it is necessary to charge it, how often do it, and whether it is always necessary to take it for this. Any battery needs a periodic charging and, mostly, it takes to remove it - for example, with mandatory maintenance.
Charging will also be charged if it just sat down, and is not able to ensure the adequate force of the starting current. This often happens when any electrical appliance - radio, headlights or dimensions, interior lighting work in the car. In other cases, it is not required to charge the battery. Subject to regular control of the battery voltage, which it is recommended to carry out 4-5 times a year. To do this, it is enough to use an ordinary ammeter. In the cold time, the frequency of control can be increased.
Charging the battery - shoot with a car or not
In general, it is much more convenient to charge the battery, which is removed from the car. So it can be carefully examined for damage to the body, clean, check the level of electrolyte and its density - and everything in comfortable conditions. But here is the owners of cars with a huge number of complex electronics try not to do this, motivating possible problems with electronics arising after the charged battery will return to its place. In fairness it should be noted that such fears have the soil.
The fact is that most complex side electronics are extremely sensitive to power outage. There are quite a few cases when the newly supplied battery detected sensors, controllers or on-board computer. Owners of such cars by all truths and inconsistencies are trying to charge the battery without removing from the car. Either they are started to another extreme - they do not charge the installed battery at all, hoping that it will make the side charging system.
This is not so. The fact is that during the engine operation, the battery is recharged by the generator. But it is necessary to ensure maximum safety of the process. In order for the gas selection process to be controlled and did not exceed normal values, a special regulator is located next to the generator, responsible for ensuring that the charge current does not exceed 14 V, while 14.5 V. is needed for complete battery charging. In this way the battery in the car never is charged 100%
Proper battery charging without removal
So, the answer to the question is whether the battery can be charged, without removing the terminals - yes. Therefore, you need to understand how to make it right, quickly and safely. To begin with, it is worth to keep in mind the fact that even the ignition key extracted from the lock does not block the power supply to some devices. Fine, The supply voltage of all auto electronics does not exceed 12 V, while charging current for the battery is 1.5-16 V.Therefore, if there is no certainty that all electronics are de-energized, it makes sense to remove the minus terminal from the battery - this will allow you to save the devices.
Carrying out the battery, without removing it from the car, it is necessary to act as follows:
- release the battery from the protective cover, remove the metal bolts, clean the upper surface, including the conclusions;
- check the level of electrolyte, when it is short enough, be sure to fill the lack of distilled water - otherwise the 100% charge will not be;
- prepare a charger - it must be disconnected from the network, when connected to strictly monitor the observance of polarity;
- turn on the charger to the network.
Attention! With this method of charging the battery, it is unacceptable to use homemade or outdated models of charging devices, since it is extremely important to provide a "high-quality" current and accurate maintenance of the desired voltage. Only so you can charge the battery without removing from the car.
What time is required for high-quality charging
If you charge the battery, without removing the terminals, it is definitely possible, then with the time it is required to fully charge everything is not so unambiguous. The time that will be required to charge each battery is different. So, especially powerful batteries are charged much longer than the batteries of small containers. At the time of complete charging, it affects the degree of its discharge - with the complete absence of time in the battery, a lot of energy will go to his charging. Of course, the value of the charging current, and the ambient temperature, and the charger itself. You can look at the practical process of charge and its time on the video:
Masses and the purpose of charge. For example, if you need to urgently charge the battery, without removing from the car, then in order to start the engine, you can go as follows:
- disconnect the wires from it;
- connect the charger, then turn it on to the network;
- set the value of the current to the limit;
- wait 15 minutes;
- disable "Charger", connect wires and start a car.
Such a measure is forced, and too often to resort to it is not worth it. For a better and complete charge, it is better to remove the battery. After performing all the necessary preliminary actions (cleaning, checking and correction of the electrolyte), leave connected to the charger for a whole night. You do not only need to forget to leave the plugs twisted. The end of the charging cycle is best not to judge in time, but according to the charger.
Important! The arrow of its indicator must be located on the left side or on 0 or lower.
New battery - Should it be charged
The newly acquired battery can also be charged, without removing the terminals, but many motorists worries the question - or whether it is necessary to do it. It is worth starting with the fact that the new it will be only for the buyer. Until the acquisition, he could "dust" in the store for many months, and if after the purchase it will be immediately installed in the car, its power can very soon not be enough to start the engine, especially in winter. therefore it will be more correct to charge it first, and only after that start exploitation.
Regardless of which the battery is charging and how - removing the car or not, it is necessary to observe all precautions, because the wrong charge may end very much. The first thing that is important to pay close attention is good ventilation. In the process of "feeding", the battery highlights the ambient air a huge number of extremely aggressive chemical compounds. These include sulfur gas, arsenic hydrogen and many others, and besides this, a huge amount of hydrogen, with a compound with oxygen forming an explosive mixture.
In addition, it is necessary to work with the battery only in gloves, since sulfuric acid can cause deep chemical burns of the skin. Naturally, if you start the charging process with closed covers of cans, a very likely explosion of the battery. In the event that the charge is carried out homemade devices, it is necessary to remember about the approximate charge time of the charge, since the reload is also harmful to the battery, as well as full discharge.
